<p>phpMyAdmin does not apply any special security methods to the MySQL
database server. It is still the system administrator’s job to grant
permissions on the MySQL databases properly. phpMyAdmin’s <span class="guilabel">Users</span>
page can be used for this.</p>
<div class="section" id="linux-distributions">
<h2>Linux distributions<a class="headerlink" href="#linux-distributions" title="Permalink to this headline">¶</a></h2>
<p>phpMyAdmin is included in most Linux distributions. It is recommended to use
distribution packages when possible - they usually provide integration to your
distribution and you will automatically get security updates from your distribution.</p>

<p>Most Debian and Ubuntu versions include a phpMyAdmin package, but be aware that
the configuration file is maintained in <code class="docutils literal notranslate"><span class="pre">/etc/phpmyadmin</span></code> and may differ in
some ways from the official phpMyAdmin documentation. Specifically, it does:</p>
<ul class="simple">
<li><p>Configuration of a web server (works for Apache and lighttpd).</p></li>

<h2>Installing on Windows<a class="headerlink" href="#installing-on-windows" title="Permalink to this headline">¶</a></h2>
<p>The easiest way to get phpMyAdmin on Windows is using third party products
which include phpMyAdmin together with a database and web server such as
<a class="reference external" href="https://www.apachefriends.org/index.html">XAMPP</a>.</p>
<p>You can find more of such options at <a class="reference external" href="https://en.wikipedia.org/wiki/List_of_AMP_packages">Wikipedia</a>.</p>

<div class="section" id="installing-from-git">
<h2>Installing from Git<a class="headerlink" href="#installing-from-git" title="Permalink to this headline">¶</a></h2>
<p>In order to install from Git, you’ll need a few supporting applications:</p>
<ul class="simple">
<li><p><a class="reference external" href="https://git-scm.com/downloads">Git</a> to download the source, or you can download the most recent source directly from <a class="reference external" href="https://codeload.github.com/phpmyadmin/phpmyadmin/zip/QA_5_2">Github</a></p></li>
<li><p><a class="reference external" href="https://getcomposer.org/download/">Composer</a></p></li>
<li><p><a class="reference external" href="https://nodejs.org/en/download/">Node.js</a> (version 10 or higher)</p></li>
<li><p><a class="reference external" href="https://classic.yarnpkg.com/en/docs/install">Yarn</a></p></li>
</ul>
<p>You can clone current phpMyAdmin source from
<code class="docutils literal notranslate"><span class="pre">https://github.com/phpmyadmin/phpmyadmin.git</span></code>:</p>
<div class="highlight-sh notranslate"><div class="highlight"><pre><span></span>git clone https://github.com/phpmyadmin/phpmyadmin.git
</pre></div>
</div>
<p>Additionally you need to install dependencies using <a class="reference external" href="https://getcomposer.org">Composer</a>:</p>
<div class="highlight-sh notranslate"><div class="highlight"><pre><span></span>composer update
</pre></div>
</div>
<p>If you do not intend to develop, you can skip the installation of developer tools
by invoking:</p>
<div class="highlight-sh notranslate"><div class="highlight"><pre><span></span>composer update --no-dev
</pre></div>
</div>
<p>Finally, you’ll need to use <a class="reference external" href="https://classic.yarnpkg.com/en/docs/install">Yarn</a> to install some JavaScript dependencies:</p>
<div class="highlight-sh notranslate"><div class="highlight"><pre><span></span>yarn install --production

<div class="section" id="installing-using-composer">
<span id="composer"></span><h2>Installing using Composer<a class="headerlink" href="#installing-using-composer" title="Permalink to this headline">¶</a></h2>
<p>You can install phpMyAdmin using the <a class="reference external" href="https://getcomposer.org/">Composer tool</a>, since 4.7.0 the releases
are automatically mirrored to the default <a class="reference external" href="https://packagist.org/">Packagist</a> repository.</p>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>The content of the Composer repository is automatically generated
separately from the releases, so the content doesn’t have to be
100% same as when you download the tarball. There should be no
functional differences though.</p>
</div>
<p>To install phpMyAdmin simply run:</p>
<div class="highlight-sh notranslate"><div class="highlight"><pre><span></span>composer create-project phpmyadmin/phpmyadmin
</pre></div>
</div>
<p>Alternatively you can use our own composer repository, which contains
the release tarballs and is available at
&lt;<a class="reference external" href="https://www.phpmyadmin.net/packages.json">https://www.phpmyadmin.net/packages.json</a>&gt;:</p>
<div class="highlight-sh notranslate"><div class="highlight"><pre><span></span>composer create-project phpmyadmin/phpmyadmin --repository-url<span class="o">=</span>https://www.phpmyadmin.net/packages.json --no-dev

<div class="section" id="installing-using-docker">
<span id="docker"></span><h2>Installing using Docker<a class="headerlink" href="#installing-using-docker" title="Permalink to this headline">¶</a></h2>
<p>phpMyAdmin comes with a <a class="reference external" href="https://hub.docker.com/_/phpmyadmin">Docker official image</a>, which you can easily deploy. You can
download it using:</p>
<div class="highlight-sh notranslate"><div class="highlight"><pre><span></span>docker pull phpmyadmin
</pre></div>
</div>
<p>The phpMyAdmin server will listen on port 80. It supports several ways of
configuring the link to the database server, either by Docker’s link feature
by linking your database container to <code class="docutils literal notranslate"><span class="pre">db</span></code> for phpMyAdmin (by specifying
<code class="docutils literal notranslate"><span class="pre">--link</span> <span class="pre">your_db_host:db</span></code>) or by environment variables (in this case it’s up
to you to set up networking in Docker to allow the phpMyAdmin container to access
the database container over the network).</p>

<span id="docker-custom"></span><h3>Customizing configuration<a class="headerlink" href="#customizing-configuration" title="Permalink to this headline">¶</a></h3>
<p>Additionally configuration can be tweaked by <code class="file docutils literal notranslate"><span class="pre">/etc/phpmyadmin/config.user.inc.php</span></code>. If
this file exists, it will be loaded after configuration is generated from above
environment variables, so you can override any configuration variable. This
configuration can be added as a volume when invoking docker using
<cite>-v /some/local/directory/config.user.inc.php:/etc/phpmyadmin/config.user.inc.php</cite> parameters.</p>
<p>Note that the supplied configuration file is applied after <a class="reference internal" href="#docker-vars"><span class="std std-ref">Docker environment variables</span></a>,
but you can override any of the values.</p>
<p>For example to change the default behavior of CSV export you can use the following
configuration file:</p>
<div class="highlight-php notranslate"><div class="highlight"><pre><span></span><span class="o">&lt;?</span><span class="nx">php</span>

<h3>Running behind haproxy in a subdirectory<a class="headerlink" href="#running-behind-haproxy-in-a-subdirectory" title="Permalink to this headline">¶</a></h3>
<p>When you want to expose phpMyAdmin running in a Docker container in a
subdirectory, you need to rewrite the request path in the server proxying the
requests.</p>
<p>For example, using haproxy it can be done as:</p>
<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>frontend http
    bind *:80
    option forwardfor
    option http-server-close

    ### NETWORK restriction

    # /phpmyadmin
    acl phpmyadmin  path_dir /phpmyadmin
    use_backend phpmyadmin if phpmyadmin LOCALNET

backend phpmyadmin
    mode http

    reqirep  ^(GET|POST|HEAD)\ /phpmyadmin/(.*)     \1\ /\2

    # phpMyAdmin container IP
    server localhost     172.30.21.21:80
</pre></div>
</div>
<p>When using traefik, something like following should work:</p>
<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>defaultEntryPoints = [&quot;http&quot;]
[entryPoints]
  [entryPoints.http]
  address = &quot;:80&quot;

      regex = &quot;(http:\\/\\/[^\\/]+\\/([^\\?\\.]+)[^\\/])$&quot;
      replacement = &quot;$1/&quot;

[backends]
  [backends.myadmin]
    [backends.myadmin.servers.myadmin]
    url=&quot;http://internal.address.to.pma&quot;

for example, FTP.</p></li>
<li><p>Ensure that all the scripts have the appropriate owner (if PHP is
running in safe mode, having some scripts with an owner different from
the owner of other scripts will be a problem). See <a class="reference internal" href="faq.html#faq4-2"><span class="std std-ref">4.2 What’s the preferred way of making phpMyAdmin secure against evil access?</span></a> and

<h3>Manually creating the file<a class="headerlink" href="#manually-creating-the-file" title="Permalink to this headline">¶</a></h3>
<p>To manually create the file, simply use your text editor to create the

loads the default configuration values and then overrides those values
with anything found in <code class="file docutils literal notranslate"><span class="pre">config.inc.php</span></code>. If the default value is
okay for a particular setting, there is no need to include it in
<code class="file docutils literal notranslate"><span class="pre">config.inc.php</span></code>. You’ll probably need only a few directives to get going; a

<p>Since July 2015 all phpMyAdmin releases are cryptographically signed by the
releasing developer, who through January 2016 was Marc Delisle. His key id is
0xFEFC65D181AF644A, his PGP fingerprint is:</p>

<p>Beginning in January 2016, the release manager is Isaac Bennetch. His key id is

<div class="highlight-console notranslate"><div class="highlight"><pre><span></span><span class="go">3D06 A59E CE73 0EB7 1B51 1C17 CE75 2F17 8259 BD92</span>

<p>Some additional downloads (for example themes) might be signed by Michal Čihař. His key id is

</div>
<p>and you can get more identification information from &lt;<a class="reference external" href="https://keybase.io/nijel">https://keybase.io/nijel</a>&gt;.</p>
<p>You should verify that the signature matches the archive you have downloaded.
This way you can be sure that you are using the same code that was released.
You should also verify the date of the signature to make sure that you
downloaded the latest version.</p>
<p>Each archive is accompanied by <code class="docutils literal notranslate"><span class="pre">.asc</span></code> files which contain the PGP signature
for it. Once you have both of them in the same folder, you can verify the signature:</p>
<div class="highlight-console notranslate"><div class="highlight"><pre><span></span><span class="gp">$</span> gpg --verify phpMyAdmin-4.5.4.1-all-languages.zip.asc

<span class="go">gpg: Can&#39;t check signature: public key not found</span>
</pre></div>
</div>
<p>As you can see gpg complains that it does not know the public key. At this
point, you should do one of the following steps:</p>
<ul class="simple">
<li><p>Download the keyring from <a class="reference external" href="https://files.phpmyadmin.net/phpmyadmin.keyring">our download server</a>, then import it with:</p></li>

</div>
<p>This will improve the situation a bit - at this point, you can verify that the
signature from the given key is correct but you still can not trust the name used
in the key:</p>

<p>The problem here is that anybody could issue the key with this name.  You need to
ensure that the key is actually owned by the mentioned person.  The GNU Privacy
Handbook covers this topic in the chapter <a class="reference external" href="https://www.gnupg.org/gph/en/manual.html#AEN335">Validating other keys on your public
keyring</a>. The most reliable method is to meet the developer in person and
exchange key fingerprints, however, you can also rely on the web of trust. This way
you can trust the key transitively though signatures of others, who have met
the developer in person.</p>
<p>Once the key is trusted, the warning will not occur:</p>
<div class="highlight-console notranslate"><div class="highlight"><pre><span></span><span class="gp">$</span> gpg --verify phpMyAdmin-4.5.4.1-all-languages.zip.asc

<p>Should the signature be invalid (the archive has been changed), you would get a

etc.) you need to create a set of special tables.  Those tables can be located
in your own database, or in a central database for a multi-user installation
(this database would then be accessed by the controluser, so no other user
should have rights to it).</p>
<div class="section" id="zero-configuration">
<span id="zeroconf"></span><h3>Zero configuration<a class="headerlink" href="#zero-configuration" title="Permalink to this headline">¶</a></h3>
<p>In many cases, this database structure can be automatically created and
configured. This is called “Zero Configuration” mode and can be particularly
useful in shared hosting situations. “Zeroconf” mode is on by default, to
disable set <span class="target" id="index-25"></span><a class="reference internal" href="config.html#cfg_ZeroConf"><code class="xref config config-option docutils literal notranslate"><span class="pre">$cfg['ZeroConf']</span></code></a> to false.</p>
<p>The following three scenarios are covered by the Zero Configuration mode:</p>
<ul class="simple">
<li><p>When entering a database where the configuration storage tables are not
present, phpMyAdmin offers to create them from the Operations tab.</p></li>
<li><p>When entering a database where the tables do already exist, the software
automatically detects this and begins using them. This is the most common
situation; after the tables are initially created automatically they are
continually used without disturbing the user; this is also most useful on
shared hosting where the user is not able to edit <code class="file docutils literal notranslate"><span class="pre">config.inc.php</span></code> and
usually the user only has access to one database.</p></li>
<li><p>When having access to multiple databases, if the user first enters the
database containing the configuration storage tables then switches to
another database,
phpMyAdmin continues to use the tables from the first database; the user is
not prompted to create more tables in the new database.</p></li>
</ul>
</div>
<div class="section" id="manual-configuration">
<h3>Manual configuration<a class="headerlink" href="#manual-configuration" title="Permalink to this headline">¶</a></h3>
<p>Please look at your <code class="docutils literal notranslate"><span class="pre">./sql/</span></code> directory, where you should find a
file called <em>create_tables.sql</em>. (If you are using a Windows server,
pay special attention to <a class="reference internal" href="faq.html#faq1-23"><span class="std std-ref">1.23 I’m running MySQL on a Win32 machine. Each time I create a new table the table and column names are changed to lowercase!</span></a>).</p>

<ul class="simple">
<li><p>upgraded to MySQL 4.1.2 or newer, please use
<code class="file docutils literal notranslate"><span class="pre">sql/upgrade_tables_mysql_4_1_2+.sql</span></code>.</p></li>

<li><p>upgraded to phpMyAdmin 4.7.0 or newer from 4.3.0 or newer,
please use <code class="file docutils literal notranslate"><span class="pre">sql/upgrade_tables_4_7_0+.sql</span></code>.</p></li>
</ul>
<p>and then create new tables by importing <code class="file docutils literal notranslate"><span class="pre">sql/create_tables.sql</span></code>.</p>
<p>You can use your phpMyAdmin to create the tables for you. Please be
aware that you may need special (administrator) privileges to create
the database and tables, and that the script may need some tuning,
depending on the database name.</p>
<p>After having imported the <code class="file docutils literal notranslate"><span class="pre">sql/create_tables.sql</span></code> file, you
should specify the table names in your <code class="file docutils literal notranslate"><span class="pre">config.inc.php</span></code> file. The
directives used for that can be found in the <a class="reference internal" href="config.html#config"><span class="std std-ref">Configuration</span></a>.</p>
<p>You will also need to have a controluser
(<span class="target" id="index-26"></span><a class="reference internal" href="config.html#cfg_Servers_controluser"><code class="xref config config-option docutils literal notranslate"><span class="pre">$cfg['Servers'][$i]['controluser']</span></code></a> and

with the proper rights to those tables. For example you can create it
using following statement:</p>

<p><a class="reference internal" href="glossary.html#term-HTTP"><span class="xref std std-term">HTTP</span></a> and cookie authentication modes are recommended in a <strong>multi-user
environment</strong> where you want to give users access to their own database and
don’t want them to play around with others. Nevertheless, be aware that MS
Internet Explorer seems to be really buggy about cookies, at least till version
6. Even in a <strong>single-user environment</strong>, you might prefer to use <a class="reference internal" href="glossary.html#term-HTTP"><span class="xref std std-term">HTTP</span></a>
or cookie mode so that your user/password pair are not in clear in the
configuration file.</p>
<p><a class="reference internal" href="glossary.html#term-HTTP"><span class="xref std std-term">HTTP</span></a> and cookie authentication
modes are more secure: the MySQL login information does not need to be
set in the phpMyAdmin configuration file (except possibly for the

However, keep in mind that the password travels in plain text unless
you are using the HTTPS protocol. In cookie mode, the password is
stored, encrypted with the AES algorithm, in a temporary cookie.</p>
<p>Then each of the <em>true</em> users should be granted a set of privileges
on a set of particular databases. Normally you shouldn’t give global

suggested, perhaps a <a class="reference internal" href="glossary.html#term-.htaccess"><span class="xref std std-term">.htaccess</span></a> file with the HTTP-AUTH directive or disallowing

<span id="securing"></span><h2>Securing your phpMyAdmin installation<a class="headerlink" href="#securing-your-phpmyadmin-installation" title="Permalink to this headline">¶</a></h2>
<p>The phpMyAdmin team tries hard to make the application secure, however there
are always ways to make your installation more secure:</p>
<ul>
<li><p>Follow our <a class="reference external" href="https://www.phpmyadmin.net/security/">Security announcements</a> and upgrade
phpMyAdmin whenever new vulnerability is published.</p></li>
<li><p>Serve phpMyAdmin on HTTPS only. Preferably, you should use HSTS as well, so that
you’re protected from protocol downgrade attacks.</p></li>
<li><p>Ensure your PHP setup follows recommendations for production sites, for example
<a class="reference external" href="https://www.php.net/manual/en/errorfunc.configuration.php#ini.display-errors">display_errors</a>
should be disabled.</p></li>
<li><p>Remove the <code class="docutils literal notranslate"><span class="pre">test</span></code> directory from phpMyAdmin, unless you are developing and need a test suite.</p></li>
<li><p>Remove the <code class="docutils literal notranslate"><span class="pre">setup</span></code> directory from phpMyAdmin, you will probably not
use it after the initial setup.</p></li>
<li><p>Properly choose an authentication method - <a class="reference internal" href="#cookie"><span class="std std-ref">Cookie authentication mode</span></a>
is probably the best choice for shared hosting.</p></li>
<li><p>Deny access to auxiliary files in <code class="file docutils literal notranslate"><span class="pre">./libraries/</span></code> or
<code class="file docutils literal notranslate"><span class="pre">./templates/</span></code> subfolders in your webserver configuration.
Such configuration prevents from possible path exposure and cross side
scripting vulnerabilities that might happen to be found in that code. For the
Apache webserver, this is often accomplished with a <a class="reference internal" href="glossary.html#term-.htaccess"><span class="xref std std-term">.htaccess</span></a> file in
those directories.</p></li>
<li><p>Deny access to temporary files, see <span class="target" id="index-50"></span><a class="reference internal" href="config.html#cfg_TempDir"><code class="xref config config-option docutils literal notranslate"><span class="pre">$cfg['TempDir']</span></code></a> (if that
is placed inside your web root, see also <a class="reference internal" href="config.html#web-dirs"><span class="std std-ref">Web server upload/save/import directories</span></a>.</p></li>
<li><p>It is generally a good idea to protect a public phpMyAdmin installation
against access by robots as they usually can not do anything good there. You
can do this using <code class="docutils literal notranslate"><span class="pre">robots.txt</span></code> file in the root of your webserver or limit
access by web server configuration, see <a class="reference internal" href="faq.html#faq1-42"><span class="std std-ref">1.42 How can I prevent robots from accessing phpMyAdmin?</span></a>.</p></li>
<li><p>In case you don’t want all MySQL users to be able to access
phpMyAdmin, you can use <span class="target" id="index-51"></span><a class="reference internal" href="config.html#cfg_Servers_AllowDeny_rules"><code class="xref config config-option docutils literal notranslate"><span class="pre">$cfg['Servers'][$i]['AllowDeny']['rules']</span></code></a> to limit them
or <span class="target" id="index-52"></span><a class="reference internal" href="config.html#cfg_Servers_AllowRoot"><code class="xref config config-option docutils literal notranslate"><span class="pre">$cfg['Servers'][$i]['AllowRoot']</span></code></a> to deny root user access.</p></li>
<li><p>Enable <a class="reference internal" href="two_factor.html#fa"><span class="std std-ref">Two-factor authentication</span></a> for your account.</p></li>
<li><p>Consider hiding phpMyAdmin behind an authentication proxy, so that
users need to authenticate prior to providing MySQL credentials
to phpMyAdmin. You can achieve this by configuring your web server to request
HTTP authentication. For example in Apache this can be done with:</p>
<div class="highlight-apache notranslate"><div class="highlight"><pre><span></span><span class="nb">AuthType</span> Basic
<span class="nb">AuthName</span> <span class="s2">&quot;Restricted Access&quot;</span>
<span class="nb">AuthUserFile</span> <span class="sx">/usr/share/phpmyadmin/passwd</span>
<span class="nb">Require</span> valid-user
</pre></div>
</div>
<p>Once you have changed the configuration, you need to create a list of users which
can authenticate. This can be done using the <strong class="program">htpasswd</strong> utility:</p>
<div class="highlight-sh notranslate"><div class="highlight"><pre><span></span>htpasswd -c /usr/share/phpmyadmin/passwd username
</pre></div>
</div>
</li>
<li><p>If you are afraid of automated attacks, enabling Captcha by
<span class="target" id="index-53"></span><a class="reference internal" href="config.html#cfg_CaptchaLoginPublicKey"><code class="xref config config-option docutils literal notranslate"><span class="pre">$cfg['CaptchaLoginPublicKey']</span></code></a> and

<p>As a workaround, a bookmarked query with the same name as the table can be created, this will
